`The invention relates to electrically heated wallie irons.

One object of the invention is to provide an improved wallie iron in which the casing members are formed of sheet metal so that the device as a whole will be comparatively light in weight, easily heated and can be" produced at a comparatively low cost.

Another object ofthe invention is to provide an electrically heated waffle iron of such efficient design and construction as to use a minimum amount of -heat to cook a given article.

Another object of the invention is to provide an electrically heated cooking utensil in which the heat developed by the heating element is conveyed as directly to the article being cooked as possible.

Another' object of the invention is to provide a waliie iron having a grid of equal thickness throughout, and having a heating element exposed vdirectly to the grid, wheref by the heat will be conveyed directly and at the same rate to all parts of the surface of the waflie.

Other, objects of the invention will appearv from the detailed description.

The invention consists in the several novel -features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is a vertical section of the invention. Fig. 2 is a detail per.

spective of one of the sheet metal lplates hereinafter referred to as grids for forming a waffle. Fig. 3 isa detail perspective of the sheet metal wall member in which -the grid is secured. Fig is a side elevation of the invention, parts being'brokenaway, showing 40 the handle or bail in a position whereby the waile iron may be readily carried. Fig. 5 is a side elevation, similar to Fig. 4, showing how the handle may be used as a lever to raisethe upper section or casing of the wale iron. Fig. 6 is a det-ail perspective of a portion of the sections, showing the clip which is used to secure the sections together when the iron is tobe carried from place to place. Fig. 7 is a perspective of one of the supporting legs.

The invention is exemplified in a Waffle iron which comprises an upper section A and a lower section B, the upper section being pivotally secured'to the lower. section and movable relatively thereto. Each section is provided with a grid 9 and an outer wall mem- 55 ber 11, both of which are formed of sheet metal. IGrrd 9 is provided with a plurality of instruck portions l0 formedin parallel rows and which are adapted to form corresponding cavities or recesses in the finishedwalfle. It will be understood that the term "waffle is intended to convey the meaning of a pancake cooked in a containerhaving a raised o`r depressed design so arranged as to form a corresponding design on the pancake. The edge of grid 9 is provided with an integrally formed flange l2 extending in the same direction and beyond the instruck portions 10 so Y that when the sections A and B are in the position shown in Fig. l, the inner surfaces of the portions 10 and grids 9 will be spaced relatively to each other thereby forming a chamber in which waflles may be cooked. The edge', of flange 12 is provided with an integral outwardly extending peripheral flange 13. Wa'll '75 member 11 is held in spaced relation from grid 9 by means of a flange 14 and forms therewith a chamber C in which a suitable electrical resistance element 17 is disposed so as to heat the grid 9. This resistance element is insulated from wall 11 by means of a sheet of asbestos or any other suitable heat insulating material. The edge of flange 14 is provided with an outwardly extending flange 15 and a peripheral flange 16 integrally formed 35 with flange 15 and form-ingtherewith a seat in whichthe flange 13 of grid 9 is disposed and secured by studs, welding or in any other suitable or like manner.

Sections A and B are pivotally secured toing vmaterialon theresistance coil, and that thls-element is not'capable of retaining anyI considerable quantity of heat, nor is it made 'm of heat resisting material. Itaccordingly does not require any appreciable quantity of heat to getthe element 1 7 hoffand there is 'no dela lin transmittingthe heat from the coilto ,t le grid; in fact, the element 17 .being g5 only a thin coating, the heat may be considered to radiate directly from the surface of the coil to the grid. It -will also beunder,

stood that the element 17 is not an essential part ofthe invention', and that'it might be an omitted altogether if desired.

' lLe 25, formed of sheet metal, areprof vide with a pluralit of upwardly extendingtongues whic extend 25" in wall member 11 of section B and are 8l bent-as at 25 to rigidl 4secure the legs thereto. These lv are a apted to support the sections `and old them at a suicient height above'a-'tablelor supporting surface sothat the heat from the resistance elements will not be ytransmitted* thereto. The lower end of ythese legs are ibent, as at 27, tomform surfaces 28 for en h the table. l 'l v j A hanl'e or bail '30 comprising a-grip 31 made of wood-and'a pair of arms 34 is disof arms 34am flared outwardly as at 34 and are pivotally secured to' flan e14I on upper Section A b means of yscrev 36 whichv extend throug "slots 34" in the arms respective` fly. By means ofthese slots, the arms may be i thrust forwardly, as shown in Fig. 5,"and the ilare'dends ofarms 34 whichl project Vbeyond ainst the flange 15,

theI screws 36`wll abut a sothatalever is formed y which the upper memberAmaygbe raised. pulling tlie arms outwardly, fas showny in otted linesin `Fig. 4, the bail or handle may be raised to a 'vertical position (shown in Fig. 4) and the I tigeth'er by means of a clip 39 which is pivoty secured to flange 15 on the upper section A and 'whichis provided with li 39 which c5 are adapted to'engage and exten around the and small heat capacity of the `i s transmitted directly to the inner surface. IA. suitable amount of waflle dough being Vplaced-in the lower half of the iron, the iron It`will be-understood that the element'117v i is merely a coating of 1a suitable heatradiat# rough slots Amay be modified within the scope posed adjacent the hinge 18.-v The inner ends wallie iron readily carried to any desiredflanges 15 so as to. hold them securely together. y p

In operation, the clip39 is released, and the iron is opened on the hinges 18. The electric heating elements 17 being in operation, heat radiates directlyto the adjacent surface ofthe grids 10. Due tothe thin construction grids, the heat is closed and securedin closed -position by the li 39, if desired.4 i

t will be noted that-the shape and formation of the grids are such that a comparatively large surface area of the wallie is exposed tothe grid, and a comparatively large surface area of the grid is also exposed to the heating element.- The heating capacity of the grid `is very small on account of its thin construction, and the heat- `is consequently 4transmitted almostimmediately to the sur- 'face of the waleor other article which is being cooked'.

It will also be noted'that due to the fact that the grid is of equal thickness Yat all points, the transferof heat will be simultaneo`us. and. at the same rate tosall parts of the surface lof the wallie. This results in inreaches a suita le tem rature for coo almost immediately, a 'r the heating elements .are put in operation,'and lwhen the cooking is done, there is a' comparatively small amount of wasted heat remaining in the cooking utensil. v

It will be seen thatI have not onl produced a cheap wale iron, but a more e cient one, both from the stand int of heat used and even transference of eat to the surface of the article which is to be cooked.

The invention is not to be understood as restricted to the details set forth, since these of the a pended claims, without departing from t e no spirit and scope of the invention. v Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:
